Another chance to hear a local band. Bristol - based indie four-strong act Fossette, who are influenced by the likes of Parcels, Phoenix and Blossoms, will be helping keep the music going as the weekend draws to a close.

Calm and understated, Bristol’s Harvey Causon isn't looking to pin your ears back with a wall of sound. You’ll be blown away instead by his soft, glitching electronica, deft take on contemporary R&B, and enthralled by his rich vocals, that sound far more world wearied than his 19 years.

Coming down from London with a fistful of major festival appearances under their belts and rave reviews from BBC Introducing and 6 Music, this bunch mix classic strings, operatic vocals, heavy beats and energetic rap. Intrigued? Then head on down to Cascade Steps.

The band was created when classically-trained Josephine became fed up with the gap between the worlds of classical and pop so decided to make something which is neither but has the best of both.

Their live performances are full of energy and their music is infectious, as audiences at WOMAD, Camp Bestival, NASS, Standon Calling, Boomtown and even Glastonbury will testify.

An economic refugee from the London hinterland, Jonny speaks words aloud, fusing bittersweet autobiography, disillusionment and wonder in an act which has established him as a firm favourite at gigs, festivals, arts centres and housing benefit offices up and down the country.

A practitioner of lo-fi rough art, he has written two books -‘The Sustainable Nihilists' Handbook’ and 'Poundland Rimbaud'- both published by Burning Eye, and both stuffed with poems, micro-fictions and threadbare philosophy.

Jonny's solo no-fi stand-up spoken word theatre show 'Man Up, Jonny Fluffypunk- OneMan's Struggle with Late-Onset Responsibility' spent 2015/16 touring around theatres, garden sheds, summer houses, empty shops and Britain's other ad-hoc performance spaces in a blatant championing of homespun DIY culture. A new show, ‘How I Came To Be Where I Never Was,’ is currently doing the same.

Bristol-based Ruby Jazz features some of the busiest local swing musicians. The past year has seen them become a popular band with the swing dance community and their performances are often accompanied by a large numbers of dancers.

Expect a splash of Sinatra, a soupcon of Ella, a hint of Basie, a touch of O'Day and a peppery and vibrant gumbo of the great American song book.. Bring your dancing shoes and a swing in your step.

R&B singer, songwriter & poet Aaliyah Esprit has had an incredible 12 month. Last year she put together a full live band for support slots with Denai Moore.
